What is the mean absolute deviation of the data set?

B

Step-by-step explanation:

x=6,8 ,15, 15, 16, ⇒ these are the set of values given

N=5 ⇒this represent the number of set of values given

Find the mean of set of values

Mean=sum of set of values/N

mean= 6+8+15+15+16=60/5 =12

find mean absolute

First find ║x-mean║⇒every set of data subtract the mean value

║x-mean║= 6, 4,3,3,4 ⇒this represents the deviations

sum of ║x-mean║=6+4+3+3+4=20

Finding mean absolute deviation

mean absolute deviation = sum of ║x-mean║÷ N where N is number of data set

N=5

20/5 =4

the answer

b. they are parallel and will never intersect.
